Who ever said multiple personality disorder was a bad thing? Certainly not ViewSonic, whose Oak Trail powered ViewPad 10Pro — which does the dual OS dance with Windows 7 and virtualized Android 2.2 — just made its way through the FCC. The government’s stamp of approval on its WiFi and AT&T-friendly WCDMA radios means it won’t fry our brains, and it shouldn’t be long before we see the 10Pro in stores. Of course, we still don’t know the price of this device… or the psychiatric costs of its OS switching ways.
